Yeah, always wise to keep a couple of bank notes in your wallet, just in case. The worst I see these days is people who carry neither cards nor cash, just their phones because "anyway I have Apple Pay/Google Wallet for contactless"... and then they use that to buy an electronic ticket on their phone for their commute to work. The day they lose their phone far from home they are instantly stranded and homeless, and they can't call anyone for help because they don't actually know anyone's phone number.
